本文提出了一种具有认知能力、高度智能的网络,称为认知网络。定义了认知网络的概念,阐述了反馈环路在认知过程中的作用,并分析了认知网络的特点。提出了一种层次化的认知网络设计的可行性方案,最后结合LTE-A中SON的特性,分析了未来网络向认知网络发展的趋势。
This paper presents a cognitive ability, highly intelligent network, known as cognitive networks. The concept of cognitive network is defined, the role of feedback loop in cognitive process is expounded, and the characteristics of cognitive network are analyzed. In this paper, a feasible scheme of hierarchical cognitive network design is proposed. Finally, according to the characteristics of SON in LTE-A, the trend of future network to cognitive network is analyzed.
